APPARATUS FOR FILLING SIPHON-BOTTLES.

Specification of Letters Patent.

Y Application filed September 2, .1909.

To all 'whom it may concern:

Be it known that I, GUY L. KENNEDY, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Apparatus for iFilling Siphon-Bottles, of which the following is a specification.

The object of the present invention is to provide an apparatus forfilling siphon bottles conveniently and rapidly.

In the accompanying drawing, Figure 1 is avertical section of one formof the apparatus, the siphon being shown in side elevation; and Fig. 2is a vertical section of another form of the apparatus.

Referring to the drawing, and especially to the forni of the inventionshown in Fig. l, 1 indicates a suitable support, to the under side ofwhich is secured a fiange 2 of a guideway 3 for a cap 4 screwed upon theupper end of a cylindrical casing 5, into the side of which is screwed apipe 6, adapted to be connected by a flexible tube 7 with a source ofsupply of aerated liquid. On the lower end of said casing 5 is screwed acap 8, formed with an outwardly flaring mouth 9, and between said lattercap and the casing is clamped the flange of a centrally apertured rubbergland 10.

The supply pipe 6 is connected'to va part of the cylinder, theinteriorof which is contracted in diameter, to form a neck, the lowerend of which forms a valve seat 11 for a valvel 12, upon the lower endof a sniff tube 13, open at both ends which passes at its upper end,first, through a rubber pack ing 14, and then through the upper cap 4,its upper open end being adapted to contact with a rubber seat 15 `in aseat plate 16, secured to said support 1. A coiled spring 17 around saidtube 13 presses at the upper end against a disk 18 secured to said tube,and at the lower end against the upper end of the contracted neck in thecasing.

Located beneath the above described aplparatus is a movable block 20,which is guided in a guideway 21, supported upon a suitable base 22, andis normally pressed upward by springs 23. In the upper surface of saidblock, immediately beneath the fiaring mouth 9, is formed a socket 24adapted to receive the extreme end ofthe head 25 of a siphon bottle,shown at 26 having a spout 27 and a lever 28 of the usual form. Theguideway 3 is formed with suitable apertures 29 for the purpose ofsniing the bottle as hereinafter explained.

Y The following is the mode of using the above described apparatus. Thesiphon bottle is inverted, and the knob on the extremity of its head isinserted into the socket 24 in the block, and the block is thendepressed against the action of the springs, until the outer end of thespout 27 can pass beneath the edge of the outwardly flaring mouth 9.Then said siphon is moved angularly until the .end of its spout iscentrally beneath said mouth, and then the springs 23 are allowed topress said siphon and spout upward. The opening through the kgland is ofsmaller di ameter than said spout, so that, as said spout is pressedupward by the action of said springs, the upper end of said spouti1npinges against the rubber surface of said gland and. moves said glandand the casing upward, its upper cap 4 sliding in the guideway 3.Thereby the seat 11 is raised from the valve 12. Immediately the aeratedliquid flows from the filling pipe through said contacted neck, pastsaid valve, through the gland, and into said siphon spout. The parts areso arranged that, when the siphon is in the angular position in whichthe valve 12 is thus opened, the siphon valve lever 28 is pressed bysaid block toward the siphon Vdischarge the compressed air. This is doneby depressing the siphon bottle and block 20 the effect of which is topermit the casing and the tube 13 to descend, closing thevvalve 12, andthe further descent of said tube removes its open upper end from therubber seat, allowing the compressed air to escape from the siphonbottle down the siphon tube, out by the spout, through the tube 13,between the upper end of said tube and the rubber seat and out by theapertures 29 in the guideway. The bottle may be then allowed to rise bythe action of said springs 23 to its former position, in which the valve12 is opened, so that a fresh supply of aerated liquid can pass into thesiphon bottle by said valve. l/hen the supply of aerated liquid hasfilled the siphon bottle up to the end of the siphon tube so that no aircan escape therefrom by sniffing, the operation is completed.

The form of the invention shown in F ig. 2 is devised for the purpose offilling siphon bottles of novel construction, for which a separateapplication for Letters Patent is filed herewith. In this form, thevalve mechanism of the apparatus does not differ from that shown in Fig. 1, but its position is inverted, the casing 5 now extending upwardfrom the guideway 3. Instead of the cap 8 having a flaring mouth, thereis now provided a cap 30 similar to the cap 8, except that in its centeris screwed a tapering filling nozzle 31. Also on account of theinversion of the arrangement of the parts in said modification, a coiledspring 32 is arranged between the seat frame and the cap to normallyraise said casing and thus perform the same function which the force ofgravity performs in the first described form' of the apparatus. Thebottle itself is partly shown at 33, and its neck is formed with aflange 34, against which rests a flange 35 of a siphon tube holder 36extending, in the inverted position of the bottle, upward from saidflange, to the center of which is secured the siphon tube 37. Againstthe flange 35 rests the flange 8S of a check'valve 39 the centralportion of which is formed of a comparatively thick shell t0 of ageneral conoidal form slitted transversely through its apex. Said Siphontube holder and check valve are held in place by a centrally aperturedcap 41 having a flange 42 bent inward over a rubber ring 113 andclamping said ring against the flange 34 of the neck.

In using this form of the invention, the bottle is inverted and ispressed downward, so that the upwardly extending end of the nozzle 31passes through the central aperture in the cap and penetrates the slitin the apex of the check valve, opening said slit. The frictionalpressure between said check valve and nozzle depresses the cylinderagainst the force of the springs 32 and 17. This has the effect ofopening the valve 12, and permitting the liquid to flow from the fillingtube into the Siphon bottle. To sniff or vent the air confined in saidsiphon bottle, the siphon bottle is raised, whereupon the spring 32raises the casing its full distance permitted by the guideway 3, theeffect of which is, not only to close the valve 12, but also to raisesaid valve and the tube 18, so that the lower end of said tube is raisedfrom off the seat 15, and the confined air can escape by the apertures29.

I claim 1. An apparatus of the character described, comprising acasing,a filling tube connected to said casing, said casing being formed at oneend with means for connecting it with a siphon bottle, a tube movable insaid casing, a valve carried by one end 0f said tube and arranged toclose the passage from said filling tube to the aforesaid end of thecasing, a fixed guideway in which said casing is slidable, a seat forclosing the other end of said tube, and a spring around said tube forholding said valve to its seat, substantially as described.

2. An apparatus of the character described, comprising a casing, afilling tube connected to said casing, said casing being formed at oneend with means for connecting it with a Siphon bottle, a valve arrangedto close the passage from said filling tube to said end of the casing, axed guideway in which said casing is slidable, a spring for holding saidvalve to its seat, a conduit leading to the atmosphere, independent ofsaid passage, and means whereby said conduit is automaticallyclosedrwhen said passage is opened, and conversely, substantially asdescribed.

In testimony whereof I have hereunto set' my hand in the presence of`two subscribing witnesses.
